A is missing the  before the penultimate semiquaver (b). Chopin noticed this patent inaccuracy while proofreading FE, yet initially the sign was erroneously inserted before the last note (d1), which was reproduced in GE1 (→GE2). In the last proofreading of FE (→EE), the  was moved to the right place, a relevant addition was also introduced in GE. In GE3 (→GE4), the superfluous sign before dwas removed.

In A there is no  raising f to f in the 7th semiquaver in the bar. This patent oversight was corrected in FE (→GE,EE).

Initially, the 1st group of semiquavers in A was . Chopin deleted it and wrote the final version below. It seems that he did not check the influence of the change on the notation of the subsequent part of the bar – there is no  before the 3rd note in the 2nd group of semiquavers, while in the 3rd group there remains a  before g, which is however justified also as a cautionary accidental, yet it was written probably due to g in the original version.

In A the only accidental in the part of the R.H. is the  before the 3rd semiquaver (c2). In a proofreading of FE (→EE), Chopin also added a  before the 2nd note (b1). It is probably a correction of the manuscript's inaccuracies, yet in this harmonic context the version with b1 (b2) as a possible original version cannot be entirely excluded. The accidentals in the 2nd group of semiquavers are included only in GE (in A, in which the middle part of the bar is written – same as in the following bars – with the octave sign, a sign or signs were not necessary).
